Well what is the molar mass of sugar?

Explanation:

We got a molar quantity of #(39.1*g)/(180.16*g*mol^-1)=0.217*mol#...

Now clearly, there are 24 atoms per molecule of glucose...and #6.022xx10^23*"atoms"*mol^-1...#

And so we take the product....

#6.022xx10^23*mol^-1xx0.217*molxx24=3.14xx10^24*"atoms".#
